General Atomics marks completion of ITER’s superconducting fusion magnet
General Atomics last week celebrated the completion of the central solenoid modules for the ITER reactor being built in southern France. Designed to demonstrate the scientific and technological feasibility of fusion power, the ITER tokamak will be the world’s largest experimental fusion facility.

The functional analysis technique is applied for estimating upper bounds of changes in eigenvalues of integral equations. In particular, the method is used to determine the value of the time decay constant resulting from perturbations in a steady-state system. The method has no restrictive limitations as to the type of operator. The applications of this method are illustrated by examples from reactor theory. The effect of changes in cross sections of a fast system on the decay constant is studied.
